Taco Bell Fights 'Where's the Beef' Lawsuit

A California woman's class-action has called into question whether Taco Bell's meat filling can be accurately labeled "beef," but Taco Belll President Greg Creed said it would not be taking this "sull[ying] of their reputation" lying down.

"Attacking a brand is like attacking a person. It's just unacceptable when there aren't any facts to support it," Creed told ABC News' George Stephanopoulos today on "Good Morning America."

The company has already begun fighting back with "swift and decisive" counterattack ad campaigns both in print and on YouTube, Creed explained, and is looking into what legal action the company can take against the plaintiff for making allegedly false statements about Taco Bell products.

But Creed said the beef is 88 percent quality USDA-inspected beef, a 'big difference" from the 35 percent beef quoted by the plaintiff.

"We have 3 percent water, 4 percent seasoning and spices," Creed told "GMA." When it came to that other nonbeef percentage, which the plaintiff claims contains "phosphates, binder and extenders, as well as other ingredients regular people do not use in recipes cooked at home," according to a statement given to ABC News, Creed would say only that any other ingredients besides beef and spices were there "for a purpose ... to enhance the flavor, the texture, the taste and all the things that make taco bell meat so tasty."

When Stephanopoulos questioned Creed specifically about one particular ingredient in the plaintiff's complaint that has caught the public's eye: isolated oat product, Creed said he could not answer why it was there because he's not a food scientist but reiterated it's there "for a purpose."

Creed said that the company would have no difficulty proving that 88 percent beef content in a court case because "the truth is on our side."
